l i `Application mea March 9,1883. `(no ninael.)

Be it known that I, JOHNWV. YOUNG, a citi-. aen of the United States, residing at 'Fort Moroni, in the county of Yavapai and Territory of Arizona, have invented certain new and useful Improvements in Metallic RailroadTies; and I do hereby declare the following tobe a `full, clear, and exact description of the `invention, such as will enable others skilled in the art to which it appertainsto makeand usel lthe same, reference beinghad to the accompalnying drawings, and to letters Vor gures of reference marked thereon, which form a part of this specification.

This invention relates to a metallictie or its object to combine cheapness and durability `of construction and greater elasticity than is possessed by metallic'railroadties heretofore known. l 1 n The invention consists in constructing a tie or sleeper of a sheetemetal plate, which is rolled or bent into a trough or U shaped body,

` land isA laid with one of its sides upon the ground. The track-rails rest upon the `uppermost plate, and are secured to the free end of the latter, so that the tie will be elastic throughout its entire length, the rail-supporting surl l face being` suitably shaped, so as to present a iirm bearing for the rails, and seats being preferably formed at thefront edge of the top plate of the tie by depressing the metal thereat. The tie is embedded in the ballast of the road in p andreceives a filling of tamped earth or other f material, so that -it will retain its shape and retain its elasticity.

The invention also consists in a tie or sleeper lconstructed of a trough or -U shaped inner plate or plates, which may be inverted for imparting additional strength to the latter, a tie of n this construction `being designed for use upon an elevated-road structure, or upon railways having a metallic or unyielding subn, p :structure or foundation.

terposed re-enforcing plate or `body `is secured A. tie having an inrails B, is constructed of `one or more sheetmetal plates bent or rolled into a trough or U form. It may suffice in lightltrafc railroads to make the tie of a single plate; "but togive greater strength and durability it is preferable to make the `tie of two or more trough or U shaped bodies placed onewithin the other, as is shown in Figure'l.`

A tie constructed of sheetmetal in themanner stated is designed to be laid upon the ground or road-bed, with one of its sides resting upon the ground, as is clearly shown in Fig. 1, anda lling, preferably oi' earth, is packed into the tie and around the frontand back' of the same, so as to firmly hold it in the ground. It is not always necessary to completely cover the tie with the ballast of the road; but, when desired, the ballast, in the form of broken stone or earth, may be packed upon the tie between the rails.

I desire` it to be` understood that, although the ballast of the road may consist entirely of broken stone, it is deemed advisable to have the filling for the ties preferably of earth.

The track-rails are supported upon thetop of the tie, orthe upper plate or member there of, and aresecured thereto by means of bolts or equivalent devices a, which engage with the base-flanges oftherails, and extend through the top of the tie, at or near itsfront or free end. The tie,V whether made of one or more plates, can be provided with elongated holes for the passage of the rail-fastening bolts or devices c, so as to permit the necessary play of the plate or plates uponthe bolts.

The top of the tie, or those portions thereofY lying under the rails, may be flattened, as

shown at a', so as to afi'ordfa bearing for the trough-shaped body, as shown in Figs.. l and IOO 2, and an interposed plate or body, G, as is seen in Figs. 3 and 4. In this instance the lower plate of the outer body or tie proper is secured to the stringers by means of bolts H, which pass through the bottom plate of the tie. Instead of bolts, I mayemploy' clips or clamps, which will rmly secure the tie to the stringers or supports and permit the top of the tie to yield or move without disturbing its bottom fastening.

In the form .of re-enforced tie shown in Figs.

3 and 4 the interposed plate or body is of similar shape as the outer member vor tie proper, but is inverted, theV back of this interposed body being made with slots 51 which receive the heads or upper ends of the bolts H, so as to secure or hold the component members of the tie by one and the same fastening device. Instead of using a single inverted interposed plate, as shown in Figs. 3 and 4, a tie adapted for solid substructures may be constructed of several layers of plates nested into each other and held together in a suitable manner, so as to possess a maximum degree of strength without destroying its elasticity.

I am aware that sheet-metal railroad-ties have heretofore been proposed; but they have used in the manner contemplated by me; and I am also aware that elastic ties composed of upper and lower flexible members are also not broadly new.

What I claim as new, and desire to secure by Letters Patent, is-

1. An elastic sheet-metal railroad-tie made of one or more troughs or U-shaped bodies, and having one of its side plates forming the top or rail-supporting portion of the tie, substantially as and for the purpose set forth;

2. The combination of an inverted re-enforc ing body or plate, U- shaped, with an outer U shaped tie adapted to support the rails upon its top, substantially as and for the purpose set forth.

3. The combination of the interposedinverted plate, having slots in its back, with the tie or outer plate, the supporting girders or string-y ers, and the bolts for holding the tie and interposed plate, substantially as and for thepurpose set forth. In testimony whereof I affix my signature in presence of two witnesses.
